git-submodule used to take care of clearing GIT_DIR whenever it operated

This only happened in very unusual contexts such as operating on the

be provoked by invoking an external tool such as "git submodule update"

Since "git fetch" learned "--all" and "--multiple" options, it has become
tempting for users to say "git pull --all". Even though it may fetch from
remotes that do not need to be fetched from for merging with the current
branch, it is handy.
"git fetch" however clears the list of fetched branches every time it
contacts a different remote. Unless the current branch is configured to
merge with a branch from a remote that happens to be the last in the list
of remotes that are contacted, "git pull" that fetches from multiple
remotes will not be able to find the branch it should be merging with.
Make "fetch" clear FETCH_HEAD (unless --append is given) and then append
the list of branches fetched to it (even when --append is not given). That
way, "pull" will be able to find the data for the branch being merged in
FETCH_HEAD no matter where the remote appears in the list of remotes to be
contacted by "git fetch".

Set transport->progress in transport.c::transport_set_verbosity() after
checking for the appropriate conditions (eg. --progress, isatty(2)),
and thereafter use it without having to check again.
The rules used are as follows (processing aborts when a rule is
satisfied):
1. Report progress, if force_progress is 1 (ie. --progress).
2. Don't report progress, if verbosity < 0 (ie. -q/--quiet).
3. Report progress if isatty(2) is 1.
This changes progress reporting behaviour such that if both --progress
and --quiet are specified, progress is reported.
In two areas, the logic to determine whether to *not* show progress is
changed to simply use the negation of transport->progress. This changes
behaviour in some ways (see previous paragraph for details).

Shell command aliases can get rather complex, and the completion
script can not always determine correctly the git command invoked by
such an alias. For such cases users might want to provide custom
completion scripts the same way like for their custom commands made
possible by the previous patch.
The current completion script does not allow this, because if it
encounters an alias, then it will unconditionally perform completion
for the aliased git command (in case it can determine the aliased git
command, of course). With this patch the completion script will first
search for a completion function for the command given on the command
line, be it a git command, a custom git command of the user, or an
alias, and invoke that function to perform the completion. This has
no effect on git commands, because they can not be aliased anyway. If
it is an alias and there is a completion function for that alias (e.g.
_git_foo() for the alias 'foo'), then it will be invoked to perform
completion, allowing users to provide custom completion functions for
aliases. If such a completion function can not be found, only then
will the completion script check whether the command given on the
command line is an alias or not, and proceed as usual (i.e. find out
the aliased git command and provide completion for it).

The bash completion script already provides support to complete
aliases, options and refs for aliases (if the alias can be traced back
to a supported git command by __git_aliased_command()), and the user's
custom git commands, but it does not support the options of the user's
custom git commands (of course; how could it know about the options of
a custom git command?). Users of such custom git commands could
extend git's bash completion script by writing functions to support
their commands, but they might have issues with it: they might not
have the rights to modify a system-wide git completion script, and
they will need to track and merge upstream changes in the future.
This patch addresses this by providing means for users to supply
custom completion scriplets for their custom git commands without
modifying the main git bash completion script.
Instead of having a huge hard-coded list of command-completion
function pairs (in _git()), the completion script will figure out
which completion function to call based on the command's name. That
is, when completing the options of 'git foo', the main completion
script will check whether the function '_git_foo' is declared, and if
declared, it will invoke that function to perform the completion. If
such a function is not declared, it will fall back to complete file
names. So, users will only need to provide this '_git_foo' completion
function in a separate file, source that file, and it will be used the
next time they press TAB after 'git foo '.
There are two git commands (stage and whatchanged), for which the
completion functions of other commands were used, therefore they
got their own completion function.

To support completion for aliases, the completion script tries to
figure out which git command is invoked by an alias. Its
implementation in __git_aliased_command() is rather straightforward:
it returns the first word from the alias. For simple aliases starting
with the git command (e.g. alias.last = cat-file commit HEAD) this
gives the right results. Unfortunately, it does not work with shell
command aliases, which can get rather complex, as illustrated by one
of Junio's aliases:
[alias]
lgm = "!sh -c 'GIT_NOTES_REF=refs/notes/amlog git log \"$@\" || :' -"
In this case the current implementation returns "!sh" as the aliased
git command, which is obviosly wrong.
The full parsing of a shell command alias like that in the completion
code is clearly unfeasible. However, we can easily improve on aliased
command recognition by eleminating stuff that is definitely not a git
command: shell commands (anything starting with '!'), command line
options (anything starting with '-'), environment variables (anything
with a '=' in it), and git itself. This way the above alias would be
handled correctly, and the completion script would correctly recognize
"log" as the aliased git command.
Of course, this solution is not perfect either, and could be fooled
easily. It's not hard to construct an alias, in which a word does not
match any of these filter patterns, but is still not a git command
(e.g. by setting an environment variable to a value which contains
spaces). It may even return false positives, when the output of a git
command is piped into an other git command, and the second gets the
command line options via $@, but options for the first one are
offered. However, the following patches will enable the user to
supply custom completion scripts for aliases, which can be used to
remedy these problematic cases.
